Theoretical Aspects of the Orientation Problem for Stereo MSS Data Coverage

Abstract

The orientation problem of MSS data is generally much more complicated than that of an optical photograph. The main reason is that MSS imagery produced from MSS data is not a central perspective representation of the ground surface, because the recording of MSS data is not instantaneous. Many studies about the geometry and the orientation problem for single MSS data coverage from aircraft have been made. Also, some effective orientation and restitution methods have already been developed by G. Konecny, et al.. Little, however, has been done in the way of investigating the orientation problem for stereo MSS data coverage from aircraft. Therefore, the author proposes in this paper an orientation technique of stereo MSS imageries based on the simultaneous determination of the exterior orientation parameters for stereo photographs. This method will soon be tested with some experimental models so as to investigate the accuracies attainable, and to clarify the difficulties in the practical analysis of stereo MSS data.
